The usb device is passed through to the VM, but I'm getting errors in a Windows VM when the device driver is loaded.

I started with a simple usb drive, on the host it is listed as:

Which I added as 0x05dc:0xc75c to the Windows 7 x64 VM.

In Windows I get an error in device manager:

USB Mass Storage Device "This device cannot start. (Code 10)"

Properties/General Tab: Device type: Universal Serial Bus Controllers, Manufacturer: Compatible USB storage device, Location: Port_#0001.Hub_#0001

Under hardware Ids: 

So it looks like the proper USB device ID is passed to the VM.

I don't see any error messages in event viewer, and I don't see anything in VDSM logs either.

Any help is appreciated.
